How to call function once only?

C# has no concept of global variables: everything is class scope.
However (just like VB) you can declare a static class and access everything in it as if they were global:

 Collapse | Copy Code

public static class Globals
   {
   public static int MyGlobalValue = 42;
   }
 
...
 

private void MyMethodSomewhereInAClass()
   {
   Console.WriteLine(Globals.MyGlobalValue);
   MyGlobalValue += 23;
   }

Technically, the class does not need to be static, but since you should not need to instatiate it, it is a good idea.


In the class file:

public static class Config

{

   

    public static bool pagerSettings;

    static Config()  //constructor

    {

        pagerSettings = false;//used for pager links

       

    }

    //get & set the pager settings

    public static bool PagerSettings

    {

        get

        {

            return pagerSettings;

        }

        set

        {

            pagerSettings = true;

        }

    }

}

From the code file:

if (Config.pagerSettings == false)

{

    Config.PagerSettings = true;

}
